Kinematic metrics and surgeon experience in robotic cholecystectomies: a pilot study on breaking down technical performance.

Background: Recent studies have correlated surgical skill measured by video-based assessment with improved clinical outcomes. Certain automated measures of operative performance in robotic surgery can be gathered beyond video review called objective performance indicators (OPIs). We explore the relationship between OPIs, surgeon experience, and postoperative recovery, hypothesizing that more efficient dissection will be associated with experience.

Kinematic data profile and clinical outcomes in robotic inguinal hernia repairs: a pilot study.

Background: Surgical training requires clinical knowledge and technical skills to operate safely and optimize clinical outcomes. Technical skills are hard to measure. The Intuitive Data Recorder (IDR), (Sunnyvale, CA) allows for the measurement of technical skills using objective performance indicators (OPIs) from kinematic event data.

The Surgical Learning Curve: Does Robotic Technical Skill Explain Differences in Operative Performance?

Prior studies on technical skills use small collections of videos for assessment. However, there is likely heterogeneity of performance among surgeons and likely improvement after training. If technical skill explains these differences, then it should vary among practicing surgeons and improve over time.

Symptomatic xanthogranuloma of the lateral ventricle in a pregnant patient treated with delayed resection: A case report and systematic review.

Intracranial xanthogranulomas (XG) are a rare benign histiocytic neoplasm and most often within the choroid. The majority are asymptomatic and are found incidentally on imaging or post-mortem examination or autopsy. We present a case of symptomatic XG in a pregnant patient who underwent a delayed transcortical, transventricular approach for lateral ventricle XG resection following the completion of her pregnancy.

Postrenal transplant infection: What is the effect of specific immunosuppressant agents?

Background: Immunosuppression is a known risk for post-transplant infections. Little data exist on the risk contributions of specific agents for various infections.

Methods: A triply robust propensity score-adjusted analysis was performed in a renal transplant cohort between February 2006 and January 2014.
